Rotation defrost
▪ Purpose
Enable continuous heating when HR modules are used.
▪
Concept
- Continuous heating is provided by performing defrost operation for each unit if HR modules are used.
- HR Only
▪
Control specifications in detail
- In heating mode, defrost operation is performed on each unit one after another according to the order of rotation priority.
(see "Rotation defrost control" for details).
Input unit Seg1 Seg2 Seg3 Seg4 Rotation defrost
Main 1 1
0 0 Disabled (default)
0 1 Enabled
▪
Notes
- Incorrect settings may seriously damage the system.
- Setting is unnecessary if high-head condition is set.
Expand operational temperature range for cooling
▪
Purpose
Extend the low temperature operation range for HR units to -15℃ .
▪
Concept
- The cooling operation range is extended by controlling purpose-specific valves on HR units.
- HR Only
▪
Control specifications in detail
- If it is difficult to secure outdoor high pressure while in cooling mode in an outdoor location with a low temperature,
formation of high pressure is facilitated by controlling the low pressure decrease, Solenoid valve.
- Main EEV, and Solenoid valve.
- Hot gas bypass.
Input unit Seg1 Seg2 Seg3 Seg4

▪
Notes
- Continuous cooling operation is possible even in low temperature condition up to -15℃ , but noise of the MCU will
increase.
- This option is only for HR unit.
Channel address
▪
Purpose
- Identify multiple main outdoor units connected to upper-level controllers, such as DMS and S-NET3.
▪
Concept
- If the Channel address is set, the same channel address is assigned to the sub outdoor units, indoor units,
and MCUs connected to a main outdoor unit.
